TOY TURBINE ENGINE.

Application filed April 2'8, 192%. Serial No. 709,618.

This invention relates to toy turbine engines.

Objects of this invention are to provide a toy steam engine which may be made with a minimum of expense, wh1ch does not require extreme accuracy in its manufacture,

and which may be most readily and simply produced.

Further objects are to provide a toy turbine engine in which the parts are so associated with the boiler that v condensation is reduced to a minimum and in which the parts are so proportioned and occupy such a relative position, that complete symmetry both as to mechanical stresses and appearance is attained.

An embodiment of the invention is shown in the accompanying drawings, in which 1- Figure 1 is a side elevation of the engine with a part of the turbine casing broken away. 7

Figure 2 is a front view of the structure shown in Figure 1, with a part of the turbine upon an ornamental relatively wide base 6 to attain the necessary security against tipping.

It is to be noted that the end caps are provided with flanges and consequently relnforce the boiler structure at the ends. Through one of these flanges a control valve 7 communicates with the interior of the boiler and a pipe 8 leads from such valve forwardly and laterally into the turbine casing. This turbine casing is PI'OVlClBdWltll an inner hollow cup shaped portion 9 1nto which the pipe 8 is threaded, preferably adjacent its upper periphery. This casing is rigidly attached to an elongated transverse bearing 10 which carries the turbine shaft 11. A' web 12 is joined to the bearing and to the bodyrportion 1 of the boiler to secure the utmost rigidity. The caslng 1s completed by an outer cap 13 WhlGh providedrwith flanges pressed or otherwise secured to the flange of the main'cup shaped portion 9 of such casing. A turbine wheel consisting of a disk 141 is rigidly carried by the shaft 11 and mounted between the portions 9 and 13 of the casing. It is provided with a peripheral reinforcing rim 15 and with a plurality of transverse dished vanes 16 earned between the bodyportion and such peripheral rim. It is to be noted from I Figure2 that the pipe 8 discharges straight across the turbine or rotor and' directly against the vanes 16. The steam passes between the disk 14 of the rotor and the outer casing13 and escapes-through a plurality of apertures 17 formed in such outer casing. A

fly wheel. 18 and a small pulley 19are rigidly attached to the other end of the shaft 11 from the turbine rotor. o v

It is to be noted that the boiler is provided with an electric heater 20 mounted thereunder which is connected by means of conductors 21 to prongs 22 carried by an insulating member 23 mounted on the support 5.

It will be seen that a turbine toy engine has beenprovlded which attains the utmost simplicity in construction, which has 'the' sof parts so positioned that maximum stability it attained as, for example, by locating the center line of the shaftfill in the central vertical plane of the boiler support and base. It will further be seen that the necessity for reciprocatory parts, valves or oscillated cylinders is wholly avoided in this toy, and

that a very smooth and rapid rotation of the apparatus is secured. i I Although theinvention has been described in considerable detaih it is to be understood that the invention may be variously e1n bodied and is, therefore, to be limited only as claimed.

Iclaim: Atoy turbine engine comprising a tubular boiler, an elongated horizontal shaft carried" thereby, a casing having a cup shaped inner portion carried by one end of said bearing,

a steam pipe" leading into the peripheral portion of said cup shaped casing and joined to said boiler, an outer'casing closing 'said cup shaped casing and provided with aplurality of apertures 'therethrough, a shaft car- 2. v geeeyrss ried by said elongated hearing, said casings extending downwardlyadgaeent One side o-f said boiler, and saideupshaped casing and beefing being braced from said boiler, a disk wardly beyond the opposite end thereof from 0 "said casing, and a fly Wheel. and pulley car- Pied by the outer end of said shaft.

in testimony that I claim the iiore 'omg I have hereunto set my hendut Mmntowoe, 11- iii A the county of Me. towec and State of JOSEPH KOENEG.
